DRIVING MECHANISM FOR CARDING-ENGINE CALENDER OR DELIVERY ROLLERS.

SPECIFICATION forming part of Letters Patent No. 455,088, dated. June 30, 1891.

Application filed February 28, 1891. Serial No. 383,313. (No model.)

T0 at whom it may concern:

Be it known that I, ROBERT ASHWORTH, a citizen of' the United States of America, residing at Providence, Rhode Island, have invented an Improved Driving Mechanism for Carding-Engine Calender or Delivery Rollers, of which the following is a specification.

My invention relates to mechanism for driving the calender or delivery rollers which draw away the dotted fleeces in carding-engines. It has been found that the delivery of the fleece from the doffer to the calenderrollers is subject to climatic and other influences, so that while at one time the fleece is drawn forward at a suitable rate at other times the fleece is not taken off with sufficient rapidity, whereby it is liable to sag or to fall down between the dotfer and the rollers. So far as I am aware, no means have hitherto been provided for effect-ing the slight variation in thespeed of the rollers, which would be required to prevent the at times excessive sagging of the fleece. I propose to obviate this defect by imparting motion to the rollers through gearing which can be readily altered to produce the required acceleration or retardation in the speed of the rollers. I employ differential gearing, which can be changed by shifting a swivel-plate carrying two intermediate gear-wheels or sets of gear-wheels, one for the ordinary speed and the other for a quicker speed.

In the accompanying drawings, Figure 1 is a front elevation of the improved motion. Fig. 2 is a plan of the same. Fig. 3 is a sectional view of a detail illustrated in outside View in Fig. 2. Figs. 4 and 5 are diagrams illustrating modifications.

In the said figures, a represents a part of the periphery of the ordinary gearwheel upon the doffer-cylinder shaft, and his the outer end of the calender-roller shaft.

To the under framing c of the engine I securca bracket cl, which carries intermediate parts of the motion and is provided with a wheel casing or shield d. To the said bracket is secured a stud e, on which is mounted a broad intermediate gear-wheel f. Upon the same stud an arm g is mounted, and upon or to the outer end of this arm a tubular stud g is formed or fixed. Upon this last-named stud a gear-wheel h is mounted, this wheel meshing with the two wheels 0. f and serving as an intermediate, whereby the wheel f is caused to revolve in the same directionas the wheel a. A bolt 2' passes through the said tubular stud and through a curved slot in g ty-four teeth and the wheel is has twenty-six teeth. Each of these'wheels meshes with an intermediate; or k, as the case may be, these intermediates being mounted to revolve upon studs Z, which are fixed to a swivel-plate m. The said swivel-plate is mounted to turn upon the axis of the roller-shaft b, so that by turning the swivel-plate in one direction or the other either one of the intermediates j is can be made to mesh with the gear-wheel f. In

the example the swivel-plate is formed with a long boss, which is turned to fit and to turn in a hole bored in the framing. In this bossis bored a bearing for the shaft 5. I have adopted this method of mounting the swivel plate, as itprovides that the plate shall be firm and steady; but I do not confine myself to such method. The swivel-plate is provided with a handle m of any suitable form, whereby the plate can be moved to change the gearing. Iprefer to limit the movements of the swivel-plate, so as to prevent thegears being caused to mesh too deeply. Fig. 3 illustrates the method I have adopted for this pur? pose. In the swivel-plate I drill three'holes, marked 1 2 3 in Figs. 1 and 8. These holes are formed on a curved line which is struck from the center of the shaft 1), so that all the holes are the same distance from such center. The holes are connected at the back of the plate by a curved slot, the ends of the holes 1 and 3 forming the ends of the slot. A sliding bolt n, mounted in a fixing n, by entering one of the holes serves to lock the swivelplate in any one of three positions, a spiral spring shooting the bolt intolocking position.

hen the swivel-plate is to be shifted, the could gear directly with the wheel a; but it bolt is drawn back; but this movement is will be seen that in such a case the movelimited, so that the bolt cannot be withdrawn ments of the swivel-plate would vary in con clear of the curved slot, which therefore limsequence of the necessity for the adjustment 5 itsthe movements of the swivel-plate. It will of the doffer.

be seen that when the bolt on is in hole 1 the IVhat I claim is:

The combination of the calender-roll the wheelj' meshing with the wheelf, whereby shaft of a carding-engine and a driving-wheel the calender-rollers will be revolved at the with a gear-wheel on said shaft, a swivel- 10 quick speed. When, however, the plate is plate, and gear-wheels carried by the latter to turned into its other extreme position and mesh with thewheel on the calender-roll'shaft the bolt shot into hole 3, the wheel 76 will and with the said driving-wheel, one of said mesh with the wheel f and the rollers will be four gear-wheels being a double gear having revolved at a slower speed. hen the bolt wheels of different diameters to transmit n10- 15 is in hole 2, the roller-shaft is disconnected tion at different speeds but in the same difrom the driving-gear, and therefore does rection to the calender-roll shaft, substannot revolve.
